DUPLICATING-MACHINE.

Application filed ()ctober 25, 1913.

To all whom it may concern:

Be it known that I, FREDERICK FRANCIS Feoiriin, a citizen of the United States, and a resident of the borough of Brooklyn, in the city and State of New York, have invented certain new and useful Improvements in Duplicatingdvlachines, of which the following is a. specification.

My invention relates to duplicating machines, and particularly to that type of such machines which are provided with an adhesive duplicating surface adapted to receive negative or reversed impressions, of matter to be duplicated.

The invention relates particularly to means co-acting with such a duplicating surface, for the purpose of applying thereto paper or the like, upon which a positive impression of the matter to be duplicated is to be transferred from the duplicating surface.

One of the principal objects of the invention is to provide means whereby the operation of transferring a number of successive positive impressions from the duplicating surface to the paper or the like provided to receive the same, may be performed more efficiently, quickly and easily than is possible by means of methods now known in the art.

The invention consists in the novel construction, arrangement and combination of various devices and parts, as hereinafter more particularly described.

In the accompanying drawings, Figure 1 is a plan view of my invention certain portions being broken away, Fig. 2 is a vertical section thereof, and Fig. 3 is a plan view of a portion thereof on an enlarged scale.

Duplicating machines of the type of which my invention is an example, are usually supported upon a base, or are contained in a case or box provided with sides. In using my invention, it is desirable to provide the base or casing of the machine with tracks or guideways, the upper edgesof which are provided with flanges projectlng inwardly at about a right angle. I have not thought it necessary to show in the accompanying drawings the base or casing of the duplicating machine, but I'have shown a portion of the flanged track or guideway on each side of the machine, the same being designated by the reference numeral 14L.

In the embodiment of my invention which I have selected for the purpose of illustration in. the accompanying drawings and descrip- Speeifieation of Letters Patent.

Patented Apr. 1th, 191?. serial No. 797,282.

tion in this specification, I provide members 16, preferably of bent sheet metal, adapted to slide on the flanges or tracks 1%. These tracks or flanges 1% are rigidly secured to the base of the machine. In Fig. 2 I have shown the duplicating surface, numbering the same 100. If desired, for the purpose of minimizing friction, said sliding members 16 may be provided with wheels 17 which are adapted to bear against the inner edge of theflanges of the said tracks ll. These members 16 are rigidly secured to a rod 20. Journaled on the rod 20, inside of the members 16, are Lshaped members 13. At the upper extremities of these L-shaped members 13 is detachably pivotally secured a roller 15, by means of pins 40 which pass through openings in the L-shaped members 13 and into sockets in the ends of the roller 15. This roller is adapted to bear a roll of paper d3 which may be unwound therefrom and wound upon another roller 19, which is journaled at the other extremities 1-1 of the above-mentioned L-shaped members 13.

I also provide a handle 22, preferably formed of a rod whose center portion is substantially parallel to the roller 15, each end portion thereof being bent at right angles to the center portion and pivotally secured to the rod 20 at a point thereon inside of the L-shaped members 13, by means of enlarged or flattened attached members 23.

Pivotally secured to these members 23 are L-shaped members 2 1, the shorter arms of which are provided with studs 25, and in the longer arms of which is journaled a roller 27. Springs 26 have one end secured to the rod 20 and the other end to the studs 25, and tend to hold said roller 27 in contact with the paper wound on the roller 19.

Tensional means may be provided to pre vent too rapid unwinding of the paper on the roller 15. These means may have the usual or any suitable form, those shown in the drawings consisting of spring pressed fingers 28, carrying a metal strip 29, which bears on the roller 15.

The operation of my invention lows:

The roller 15.is removed from the apparatus by withdrawing the pins in the ends thereof. On this roller is slipped a roll of paper or the like on to which it is desired to transfer a number of images from the duplicating surface, and the roller is reis as folplaced in the machine so that the paper will feed over the top of the roller. The tensional device is now allowed to bear on the roller to prevent too rapid unwinding of the paper thereon. The end of the'paper is now passed between the rollers 19 and 2 7 and rolled a few times around the roller 19, to insure against its unwindin The apparatus is now ready for use.

When it is desired to print a number of impressions from the duplicating surface on to the paper in the paper-carrying device, it is placed on the duplicating machine in such a manner that the members 16-will slide on the tracks 14. The bottom of the roller 19 and the surface of the paper thereon, will now rest on the printing surface of the duplicating machine. The device is placed at one end of the tracks 14, and drawn to the other end, while a downward pressure is maintained on the handle 22, insuring contact between the duplicating surface and the paper on the roller 19.

, As the device is drawn over the duplicating surface the impression from the same is transferred to the paper on the lower side of the roller 19, and at the same time the paper is wound around the roller as fast as printed. As a quick drying ink is always used with devices of this character, no blurring occurs, eventhough the paper be rewound immediately after the impression is taken thereon. When the device has been run entirely across the printing surface, the handle is raised, thus removing the paper on the roller 19 from the printing surface. The device is then run back to the other end of the duplicating surface, and the operation repeated as many times as may be desired. As the paper becomes wound around the roller 19, it is kept from slipping by the roller 27, which is continually forced against the roller 19 and the paper thereon by the-action of the springs 26.

The principal advantage of my invention lies in the increased ease and speed with which impressions may be taken over the old process of placing the paper on the duplicating surface, by hand or otherwise, one sheet at a time. Another advantage of the invention is that the rolling of the. paper around the take-up roller neutralizes the tendency of the paper to curl up as a result of its application to the duplicating surface, so that the paper when finally taken from the roll lies flat or nearly so.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is as follows:
